Title: Packing rod-shaped articles in a container
IPC: B65G57/11
Filed: 1975-08-08
Abstract: 1520911 Filling containers with rod-shaped articles JAPAN TOBACCO & SALT PUBLIC CORP [trading as JAPAN TOBACCO CORP] NEO FILTER CO Ltd and SANJO MACHINE WORKS Ltd 8 Aug 1975 [20 Aug 1974] 33104/75 Headings B8C and B8A A method of filling a container 5 with filter rods or cigarettes 60 comprises collecting the articles in a hopper 17 levelling the articles in the hopper and pushing the articles into the container by a pusher plate 14 which is upwardly raised in the centre to hinder the fall of the articles in the centre of the hopper as the plate is retracted so that the layer formation is maintained, the articles at the sides being frictionally hindered. The articles are levelled and distributed in the hopper by an upper swing pin 29 and lower swing pins 31 connected to boards loosely fitted in the back plate 24 of the hopper and reciprocated by a rod 36 through a lever 33. There are also plates (26) vibrated in unison connected to the side walls 25 of the hopper. Beneath these plates in the side walls there are further plates (53, Fig. 8, not shown) which have recesses to receive the end rod 60 in each alternate layer, the rods in adjacent layers being offset from one another. If an odd number of layers say 3, is pushed by the plate, 14 into a container, these further recessed plates (54) are provided with recesses offset by the height of a layer from the plates (53). The two sets of plates are alternately advanced after each reciprocation of the pusher plate 14. The plate 14 is advanced when there are sufficient articles in the hopper to press top plates 56, 57 against switches 61, 62. When there is an excessive accumulation of articles at the entry to the hopper a plate 58 actuates a switch 63 or a photoelectric device is actuated to speed up the vibrations of the pins 29 and 31. The articles may be fed from one or both sides into the hopper. Container feed.-Empty containers 5 in holders 4 are fed along a table 3 by a ratchet mechanism and are lowered by chains 8 past the hopper. After each reciprocation of the pusher plate 14 the chains move by an amount controlled by a photoelectric device (19, Fig. 5b, not shown) detecting holes (15a) in a disc fixed to a gear shaft of the chain and corresponding to the height of the layers of articles inserted in the container by each reciprocation of the pusher. Means 20 on an oscillating chain remove filled containers along the table 2c.

Title: Improvements in the art of producing bearings, bushings, and the like
IPC: B21K1/04
Filed: 1920-11-24
Abstract: 177,206. Chadwick, L. W. Nov. 24, 1920. Bearings.-Bearings, bushings, packing glands &c. are made by producing a tubular blank with its walls corresponding in thickness to that of the completed article and with its inner and outer radii greater than those of the completed article, dividing the blank to produce a pair of articles, reducing the radii by pressure application, and applying a setting action thereto when the desired shape and radii have been attained. The setting action is preferably of the nature of a sudden impact applied while the article is undergoing strain. The article is placed on an anvil 19, Fig. 6, and acted on by shaping dies 17, 17<a>, 18, the die 18 being preferably actuated later than the other dies. The dies 17, 17<a> produce a bending effect at the central portion, after which the die 18 corrects the deformation at this point and forces the parting surfaces of the bearing to advance downwardly between the anvil and dies. When the pressure is released, there is a partial spring back of the bearing in its original shape and size. The article is then pressed between members 21, 23, Fig. 10, and while under pressure is set by a blow from a punch 28.

Filed: 1948-12-30
Abstract: 659,005. Stands for drums or barrels. SHELL REFINING & MARKETING CO., Ltd., and REYNOLDS, E. A. Dec. 30, 1948, No. 33497. [Class 21] [Also in Group XXX] A pallet for elevating and stacking drums in horizontal position comprises a pair of lateral members joined at their ends by a pair of longitudinal members, each lateral member being curved to fit an arc of the periphery of one or more drums. The pallet comprises in one form two lateral members 10 joined longitudinally by channel girders 17, each lateral member comprising two curved tubes 12, 13 welded together at points 14 and at points between 14 by pieces 18. The lateral members may extend to any desired length, so as to support one, two or more drums 20 in the hollows formed. The hollows on the underside at the same time accommodate the upper surfaces of further drums on top of which the pallet may rest so that a stack may be formed by single layers of drums with pallets between each layer. The prongs 22, 23 of a lifting truck may be inserted as shown between tubes 12 and 13. Figs. 4 and 6 show a modification in which each lateral member comprises only lower curved tubes 30, 31 which provide hollows on this underside for accommodating the upper surfaces of drums beneath. The supporting surface for the drums upon the pallet is a pair of girders 35, 36 at the end of which collapsable chocks are placed. This pallet is used when drums are to be rolled on to a high rack in one layer. Thus the pressure on the drums is not high and the principal purpose of the curved tube is to position a plurality of layers on a fork elevating truck. Four drums 20 are rolled on to the pallet with one chock raised and the other is then raised while the pallet is elevated and one chock is subsequently lowered to allow the drums to roll out. Each chock comprises two arms 39, 40 pivoted on girders 35 and 36 respectively, their free ends being joined by a rod 38. Rod 38 supports a frame 41, 42, 43 which swings freely so as to be folded back as arms 39, 40 are lowered, or be unfolded and rest against stops 44 on the end channel girders 33 to form a rigid trestle, the lowered and raised positions being shown respectively at the left and right of Fig. 4.

Title: Process for the preparation of isoprene
IPC: C07C4/00
Filed: 1970-07-14
Abstract: 1317000 Isoprene; methylcyclohexenes; ethylene NIPPON OIL CO Ltd 14 July 1970 [28 July 1969] 34050/70 Heading C5E Isoprene is obtained by (1) isomerizing 3- and/or 4-methylcyclohexene to 1-methylcyclohexene in the presence of an alkali metal catalyst at 0-350‹ C., (2) separating 1-methylcyclohexene, and (3) thermally cracking 1- methylcyclohexene at 400-800‹ C. The alkali metal catalyst in step (1) may comprise any of the following types : (a) an alkali metal per se or an alloy thereof, in solid form or dispersed in an organic solvent or supported on alumina or silica-alumina; (b) an alkali metal/aromatic complex derived from naphthalene, anthracene, pyrene, p-terphenyl or chrysene; (c) an organometallic, e.g. butyl lithium, or allyl, amyl or benzyl sodium; (d) an alkali metal amide or substituted amide; (e) an alkali metal alkoxide or phenoxide; (f) an alkali metal oxide or hydroxide; or (g) an alkali metal/graphite complex; the alkali metal in each case being Li, Na or K. The separation step (2) is suitably fractionation, though in Example 1 the product of step (1) is extracted with n-hexane and the extract then fractionated. Step (3) is suitably non-catalytic, though a contact surface may be provided to facilitate reaction, e.g. a porous material. Ethylene is a major by-product of step (3). The examples also describe the production of starting materials for use in the above process, as follows: (Example 1) 4-methylcyclohexene is produced by reacting propylene and butylene at 300‹ C. in the presence of hydroquinone; (Example 2) mixed methylcyclohexenes are produced by dehydrating mixed methylcyclohexanols with sulphuric acid; and (Example 3) propylene is first dimerized at 360‹ C. over SiO 2 /Al 2 O 3  to produce a fraction containing methylcyclopentene, which is then thermally cracked at 800‹ C. to yield a mixture of propylene and butylene, which are then reacted together at 310‹ C. to form 4-methylcyclohexene.

Abstract: 393,960. Television. WILSON, J. C., WRIGHT, E. E., and BAIRD TELEVISION, .Ltd., 133, Long Acre, London. Dec. 9, 1931.. No. 34151. [Class 40 (iii).] In a television transmission system the frequency spectrum of the image currents is divided into a number of bands, and components lying in frequency bands except the lowest after being reduced and inverted in frequency are trans- .mitted over channels allocated to the various bands and at the receiving end are restored to their original frequency values. The frequencies forming the limits of bands are the " elided " frequencies of the scanning system which are defined as the number of times (and multiples of that number) an aperture covers its own length in the direction of traversal in one second. On the assumption of elided frequencies of 10, 20, 30 kilocylces and a number of channels passing frequencies up to 10 kilocycles, the picture signal components lying in the lowest band are transmitted directly over a channel 1 to the receiving end. The image signals are also applied to band-pass filters 15, 16 which select components in the ranges 10-20 and 20-30 kilocycles respectively, and the components so filtered are applied to modulators 6, 7 to modulate carrier currents of frequencies 20, 30 kilocycles respectively. The lower side bands which are inverted with respect to the frequency of the original signal components solely pass over the low-pass channels 2, 3. At the receiving end the signals from the lines 2, 3 are applied to modulators 9, 10 modulating frequencies of 20, 30 kilocycles respectively. The modulated currents are passed to band-pass filters 11, 12 which pass components in the bands 10-20, 20-30 kilocycles respectively proportional to the components selected by the band-pass filters 15, 16. The restored image components are then applied in combination with the components passing over the channel 1 to an amplifier 8 and a glow-discharge lamp 14. The theory of the system is discussed mathematically in the Specification. Specification 381,254 is referred to.

Abstract: 1,095,026. Gas filter. G. GRUN, [trading as GEBR. GRUN KOMM. GES], Aug. 10, 1965 [Aug. 10, 1964], No. 34230/65. Heading B1T. [Also in Division F2] Dust-laden gas is delivered by inlet (2) to a housing 1 containing a rotating drum 4 which carries rows of radially projecting hollow filter elements 6 and filtered gas is withdrawn from outlet 3 which communicates with the open end 8 of the drum. In Fig. 1 the drum is rotated intermittently by a mechanism 14, 25, 26, driven by the same motor 24 as is worm 18, to bring each axial row of cloth covered, cylindrical, basket filter elements in turn opposite fixed nozzles 20, projecting from hollow shaft 7. In each position a switch 16, actuated by holes 15 in wheel 14, initiates a supply of pulsed compressed air to nozzles 20, the length, number and total duration of pulses being variable. Elements 6 may have venturi nozzles 27 to enhance the reverse flow and may be replaced by filter candles of sintered metal or low pressure polyethylene. In Figs. 3-6, (not shown) the filter elements are of sectoral shape and may be mounted with their radial edges, of U-shaped section, engaging square tubes projecting from the drum and with circumferential straps retaining them in place to form complete hollow discs. Each element is radially subdivided, and in addition to fixed nozzles 20, further nozzles (32) may engage between adjacent elements, being aligned with nozzles 20 to apply either suction or compressed air to the outsides of the elements in line with nozzles 20. Supply to nozzles (32) may be individually controlled by pneumatic flap valves (38) whereby only one nozzle (32) may be connected during any particular revolution of the drum. In Figs. 7-9 (not shown) the drum rotates continuously and a series of triangular teeth (50) on the drum drive pulley engage an axially pivotable lever (53) in turn, whereby the shaft 7 carrying nozzles 20 rotates with the drum through a small angle to backwash each row of elements in turn, before jumping back to repeat the process with the next row. A drum may be divided by axialradial walls into sectors, and a reverse flow nozzle of sector shape, in the filtered gas outlet, engages three sectors at once as the drum rotates.
